Book excerpt: Anatomically, the central nervous system looks remarkably symmetrical--from the relatively simple structures of the spinal cord to the extensively convoluted folds of the cerebral hemispheres. At the functional level, however, there are striking differences between the left and right hemispheres. Although popular writings attribute language abilities to the left hemisphere and spatial abilities to the right, differences in hemispheric function appear to be more subtle. According to Ivry and Robertson, asymmetries over a wide range of perceptual tasks reflect a difference in strength rather than kind, with both hemispheres contributing to the performance of complex tasks, whether linguistic or spatial. After an historical introduction, the authors offer a cognitive neuroscience perspective on hemispheric specialization in perception. They propose that the two hemispheres differ in how they filter task-relevant sensory information. Building on the idea that the hemispheres construct asymmetric representations, the hypothesis provides a novel account of many laterality effects. A notable feature of the authors' work is their attempt to incorporate hemispheric specialization in vision, audition, music, and language within a common framework. In support of their theory, they review studies involving both healthy and neurologically impaired individuals. They also provide a series of simulations to demonstrate the underlying computational principles of their theory. Their work thus describes both the cognitive and neurological architecture of hemispheric asymmetries in perception.

This book was released on 2013-06-29 with total page 1016 pages. Available in PDF, EPUB and Kindle. Book excerpt: The third edition of this monograph continues to have the goal of providing an overview of current thought about the spinal cord mechanisms that are responsible for sensory processing. We hope that the book is of value to both basic and clinical neuroscientists. Several changes have been made in the presentation, as well as additions because of the research advances that have been made during the past decade. Chapters 3 and 4 in the previous edition have been subdivided, and now the morphology of primary afferent neu rons of the dorsal root ganglia is described in Chapter 3 and the chemical neuroanatomy of these neurons in Chapter 4. The description of the dorsal horn in the previous Chapter 4 is now included in Chapter 5, and the chemical neuroanatomy of the dorsal horn in Chapter 6. Furthermore, discussions of the descending control systems have now been consolidated at the end of Chapter 12. The authors would like to express their appreciation for the help provided by several individuals. R.E.C. wishes to acknowledge the many things he learned about primary afferent neurons from conversations with Dr S. N. Lawson. He also thanks Lyn Shilling for her assistance with the typing. WDW thanks Dr Nada Lawand for her critical reading of parts of the manuscript, Rosaline Leigh for help with the manuscript, and Griselda Gonzales for preparing the illustrations.

Download or read book Plasticity of primary afferent neurons and sensory processing after spinal cord injury written by Alexander Rabchevsky and published by Frontiers Media SA. This book was released on 2015-01-05 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traumatic injury of the spinal cord affects the entire organism directly and indirectly. Primary injury destroys neurons and severs axons which participate in neural circuits. Secondary injuries and pathologies arise from numerous sources including systemic inflammation, consequential damage of cutaneous, muscular, and visceral tissues, and dysregulation of autonomic, endocrine and sensory- motor functions. Evidence is mounting that spinal cord injury (SCI) affects regions of the nervous system spatially remote from the injury site, as well as peripheral tissues, and alters some basic characteristics of primary afferent cell biology and physiology (cell number, size/frequency, electrophysiology, other). The degree of afferent input and processing above the lesion is generally intact, while that in the peri-lesion area is highly variable, though pathologies emerge in both regions, including a variety of pain syndromes. Primary afferent input to spinal regions below the injury and the processing of this information becomes even more important in the face of complete or partial loss of descending input because such spared sensory processing can lead to both adaptive and pathological outcomes. This issue hosts review and research articles considering mechanisms of plasticity of primary afferent neurons and sensory processing after SCI, and how such plasticity contributes to sparing and/or recovery of functions, as well as exacerbation of existing and/or emergent pathologies. A critical issue for the majority of the SCI community is chronic above-, peri-, and below-level neuropathic pain, much of which may arise, at least in part, from plasticity of afferent fibers and nociceptive circuitry. For example, autonomic dysreflexia is common hypertensive syndrome that often develops after SCI that is highly reliant on maladaptive nociceptive sensory input and processing below the lesion. Moreover, the loss of descending input leaves the reflexive components of bladder/bowel/sexual function uncoordinated and susceptible to a variety of effects through afferent fiber plasticity. Finally, proper afferent feedback is vital for the effectiveness of activity-dependent rehabilitative therapies, but aberrant nociceptive input may interfere with these approaches since they are often unchecked due to loss of descending modulation.

Available in PDF, EPUB and Kindle. Book excerpt: The field of perception is devoted to explaining the operation of the senses and the experiences and behaviors resulting from stimulation of the senses. Perceptual processes such as recognizing faces, seeing color, hearing music, and feeling pain represent the actions of complex mechanisms, yet we usually do them easily. The Encyclopedia of Perception presents a comprehensive overview of the field of perception through authoritative essays written by leading researchers and theoreticians in psychology, the cognitive sciences, neuroscience, and medical disciplines. It presents two parallel and interacting approaches: the psychophysical, or determining the relationship between stimuli in the environment and perception, and the physiological, or locating the biological systems responsible for perception. Are there any processes not associated with perception? Surely there are, but the pervasiveness of perception is truly impressive, and the phenomena of perception and its mechanisms are what this encyclopedia is about. Key Features Contains 16 pages of color illustration and photography to accompany the entries Offers a varied and broad list of topics, including basic research as well as methodologies, theoretical approaches, and real-world applications of perceptual research Emphasizes human perception but includes ample research because of its importance in its own right and because of what this research tells us about human perception Written by recognized experts from many disciplines but for an audience with no previous background in perception—students and members of the general public alike Key Themes Action Attention Audition Chemical Senses Cognition and Perception Computers and Perception Consciousness Disorders of Perception Illusory Perceptions Individual Differences (Human) and Comparative (Across Species; Not Including Ageing, Disorders, and Perceptual Development) Methods Perceptual Development/Experience Philosophical Approaches Physiological Processes Sense Interaction Skin and Body Senses Theoretical Approaches Visual Perception

Download or read book Semantic Perception Theory written by Kekang He and published by Springer Nature. This book was released on 2019-11-26 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: Based on an in-depth study of children’s language development theory, this book puts forward the original proposition that semantic perception is the human sixth sense. Presenting a detailed, complete, and scientific argumentation, it asserts that the innateness of semantic perception has a physiological basis and that language acquisition is based on semantic perception, and proposes the idea of a critical period of nurture and language growth. To this end, the book not only contrasts children’s language acquisition processes and the process of adult speech generation and comprehension, but also discusses the ability to read and write, describing this important stage of children’s language development and analyzing semantic perception. Focusing on education and psychology, it also discusses the use of semantic perception theory to instruct teaching and learning. This book is a valuable resource for teachers, researchers, practitioners and graduate students in the fields of educational technology, child development and language learning, as well as anyone interested in children’s language development.

This book was released on 2012-12-06 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book constitutes the proceedings of a NATO Advanced Research Workshop held in El Escorial (Spain) from 22 -27 May 1988 with the title Processing of sensory information in the superficial dorsal hom of the spinal cord. Included in the book are reports of most of the main lectures given at the meeting, section introductions written by each session Chairman, section reports compiled by session rapporteurs and some short papers invited from authors of communications given in poster form. The latter were selected on the basis of being immediately relevant to the topic of the workshop and of originating from a laboratory not represented by the main speakers. All in all we believe that the reader can get a fair idea of the structure and general character of this Workshop. The overall aim of the meeting was to review the current state of knowledge on the role of the superficial dorsal horn of the mammalian spinal cord as a nucleus of relay and modulation of the somatic and visceral sensory input to the central nervous system. In this context, the contribution of this spinal cord region to the appreciation of pain was a central topic of discussion. Over the last decade there has been a considerable increase in anatomical, physiological and neurochemical studies of the superficial dorsal horn.

Available in PDF, EPUB and Kindle. Book excerpt: Spinal cord stimulators (SCS) are implantable medical devices used to treat chronic pain of neurologic origin, such as sciatica, intractable back pain, and diabetic. The device generates an electric pulse near the spinal cord's dorsal surface, providing a parasthesia sensation that alters the perception of pain by the patient, and is typically used in conjunction with conventional medical management.

Download or read book Understanding Pain written by Fernando Cervero and published by MIT Press. This book was released on 2012-08-17 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: An expert explores the biological and emotional nature of pain: why it hurts and why some pain is good and some pain is bad. If you touch something hot, it hurts. You snatch your hand away from the hot thing immediately. Obviously. But what is really happening, biologically—and emotionally? In Understanding Pain, Fernando Cervero explores the mechanisms and the meaning of pain. When you touch something hot, your brain triggers a reflex action that causes you to withdraw your hand, protecting you from injury. That kind of pain, Cervero explains, is actually good for us; it acts as an alarm that warns us of danger and keeps us away from harm. But, Cervero tells us, not all pain is good for you. There is another kind of pain that is more like a curse: chronic pain that is not related to injury. This is the kind of pain that fills pain clinics and makes life miserable. Cervero describes current research into the mysteries of chronic pain and efforts to develop more effective treatments. Cervero reminds us that pain is the most common reason for people to seek medical attention, but that it remains a biological enigma. It is protective, but not always. Its effects are not only sensory but also emotional. There is no way to measure it objectively, no test that comes back positive for pain; the only way a medical professional can gauge pain is by listening to the patient's description of it. The idea of pain as a test of character or a punishment to be borne is changing; prevention and treatment of pain are increasingly important to researchers, clinicians, and patients. Cervero's account brings us closer to understanding the meaning of pain.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this monograph is to provide an overview of current thought about spinal cord mechanisms for sensory processing. We hope that the book will be useful both to basic neuroscientists and to clinicians. So me historical aspects of the problem and a few definitions are treated in the first chapter. The second chapter reviews the organiza tion of the peripheral nervous system from the standpoint of sensory receptors and primary afferent axons. The third chapter is concerned with what is known about the structure of the dorsal horn, while the fourth chapter considers the activity of dorsal horn interneurons. The clinical, behavioral, and neurophysiological evidence for what parts of the cord white matter contain particular sensory pathways is discussed in Chapter 5, and details about the various pathways in the dorsal columns, the dorsolateral fasciculus, and the ventral quadrant form the . subject matter of Chapters 6 through 8. The final chapter is an attempt to summarize what is presently known about the receptors and the spinal cord pathways responsible for the sensations of touch-pressure, flutter-vibration, pain, temperature, position sense and visceral sensa tion and about descending control systems.
Download or read book Spinal Afferent Processing written by T.L. Yaskh and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 564 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some 29 scientists from the fields of neuroanatomy, neurochemistry, neu rophysiology, neuropharmacology, and behavior have contributed their ef forts to this testimonial on behalf of the contributions made by Dr. F. W. L. Kerr to science and to those with whom he interacted. The intention of the contributors to this volume was to deal with the manifold advances that pertain to the substrates in spinal cord relating to the processing of sensory infor mation, a subject that in one form or another provoked time and again Kerr's native enthusiasm for research. The organization of the book follows a natural course from the peripheral innervation of the somatic and visceral organs (Winkelmann, Chapter 2) to the effective stimuli that activate these fibers and give rise to sensation under normal and pathological conditions (Campbell and Meyer, Chapter 3; Dubner and colleagues, Chapter 13; Dyck, Chapter 14) to the course these afferent systems take to enter the spinal cord (Coggeshall, Chapter 4) and to the organization of the systems through which this afferent information reaches the brain (Willis, Chapter 11; Vierck and colleagues, Chapter 12).
